以K2S2O8-NaHSO3氧化还原体系为引发剂合成羟乙基纤维素与丙烯酰胺的接枝共聚物,探讨反应时间、反应温度、引发剂用量对接枝共聚物特性黏数的影响,采用红外光谱(FI-IR)对聚合物进行结构表征,用热重分析法(TGA)分析接枝聚合物的热稳定性。
The graft copolymer of hydroxyethylcellulose and acrylamide was synthesized using K2S2O8-NaHSO3 redox system as initiator, and the effects of reaction time, reaction temperature and initiator on the intrinsic viscosity of graft copolymer were discussed. FI-IR) was used to characterize the structure of the polymer. The thermal stability of the grafted polymer was analyzed by thermogravimetric analysis (TGA).
